Title: Polygonal wrench and tightening tool
Inventor: MORITA MITSUO
IPC: B25B13/56
Filed: 1999-02-18
Abstract: PROBLEM TO BE SOLVED: To provide a polygonal wrench, a tightening tool combined with the polygonal wrench, and a tightening tool for handling the polygonal wrench, which can improve the tightening and removing work efficiency of a clamp, when an obstacle exists on a rotation trajectory of a long shank to be seized, or a short shank, or when rotation-engaging operation is repeated in bad visibility condition. SOLUTION: A hexagonal wrench 1 is formed in a straight line without a bend, and has a sphere portion 1c with hexagonal edges at one end thereof. Even if the hexagonal wrench 1 is inserted into a hexagonal hole 6a of a clamp 6 with a slight inclination, it is possible to engage the sphere portion 1c with the hexagonal hole 6a to thereby temporarily tighten the clamp 6. When carrying out the actual tightening, the other end of the hexagonal wrench 1 opposite to the sphere portion 1c is engaged with the hexagonal hole 6a of the clamp 6. A ratchet wrench 2 has a seizing portion 2a, a socket 2b, and a ratchet mechanism 2c disposed on one end of the seizing portion 2a for controlling a rotation direction of the outer peripheral surface while rotatably supporting an outer peripheral surface of the socket 2b.

Abstract: PURPOSE:To record with accurate track intervals by combining a carriage error signal corresponding to the shift of the emission position of a carriage in its radial direction and a disk error signal corresponding to the shift of the disk in its radial direction and generating an error signal from the combined signals. CONSTITUTION:The laser beam from a laser light source 61 is split into two parts by means of a beam splitter 65 and the beams enter a side end face of a disk 1 and a carriage 5 by way of interference meters 63 and 66. The reflected beam of the disk 1 enters a disk position detection section 67 by way of the interference meter 66 and is compared with reference data at that detection section 67, thereby producing a differential disk error signal epsilond. In the same fashion, a carriage position detection section 64 compares the reflected beam of a carriage 65 with designated position data from a carrier signal generation circuit 8 and outputs a differential carriage error signal epsilona. The signals epsilond and epsilona are combined by a combining circuit 68 and provides an error signal epsilont signal to a drive circuit 7 so as to control the carriage 5. This construction makes it possible to record data with an accurate truck span.

IPC: B09C1/10
Filed: 1999-02-18
Abstract: PROBLEM TO BE SOLVED: To visualize a flow of a gas in soil by injecting the gas in the soil by adding a coloration reagent and color identifying it. SOLUTION: As a coloration reagent, a reagent which is colorless in an initial state but brings about a color reaction when a specific gas is applied, a hydrogen ion concentration reagent which color identifies in an initial state but becomes another color or colorless by a specific gas or the like is used. Soil 3 obtained by mixing cement suspension supernatant colored with red by a phenol phthalein of a coloration reagent with cement mixed fine sand is contained in a transparent acrylic column 1, a pressure reducing valve 8 is regulated, and a carbonic acid gas is sent from a gas cylinder 9 into the soil 3 while holding a flow rate of a flowmeter 6 constant. After the gas is sent, the soil 3 is urged out from the column 1, sliced at about each 5 cm, and its section is observed.  Then, though the soil 3 before the gas is sent is red by the phenol phthalein, but after the gas is fed, a part brought into contact with the carbonic acid gas becomes colorless by a neutralization. Accordingly, a flowing state of the gas is observed from its color erasing state.

Title: Optical pulse tester
Inventor: IZUMIDA CHIKASHI
IPC: G01M11/02
Filed: 1993-03-01
Abstract: PURPOSE:To generate a high output optical pulse and to perform a high dynamic range by inputting an optical pulse divided and output from an optical divider, forming and outputting it at a timing matching to its peak. CONSTITUTION:An optical pulse to be divided and output from an optical demultiplexer 16 in a Q switching laser has a side lobe at a pulse having a peak power as a center. When the pulse of this state is tested as an output of optical pulse generating means 10, distance resolution is deteriorated. Accordingly, the pulse to be divided and output from the laser is shaped at its peak as a center by using an optical switch 18. Thus, a high output pulse is generated. The switch 18 receives a synchronizing signal of a timing generator 31 to be operated similarly to an optical switch 15 in the laser. The timing is so controlled as to be turned ON by the peak of the pulse divided and output from the laser.

Title: Thermal transfer sheet
Inventor: MAZAKI HIDEHIKO
IPC: B41M5/382
Filed: 1989-02-22
Abstract: PURPOSE:To increase the capability to become resistant to contamination and to resolve an image by forming a mold releasing-type resin layer containing a constituent at a specific, thermally deforming temperature on the surface of an ink layer. CONSTITUTION:A mold-releasing resin layer containing a constituent at a thermally deforming temperature of 100 deg.C or less is formed on the surface of an ink layer. That is, if resin which forms a thermally porous surface layer but deforms thermally at 100 deg.C or more is used, fi ne pores do not form or coarse pores form on the surface layer due to heat from a thermal head. In addition, if the temperature is 50 deg.C or less, handling a thermal transfer becomes difficult. Furthermore, the resin does not become porous so easily in proportion to a calorific value. The preferable thickness of the surface layer should be 0.05mum or more and 5mum or less. If the ink layer is for instance, formed to be 2 to 7mum, a thermal transfer sheet for printing only once can be obtained. In addition, if the ink layer is 5 to 20mum, a thermal transfer sheet for printing many times can be obtained.

Title: Plate for transmission chain
Inventor: YOSHIDA OSAMU
IPC: F16G13/06
Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To reduce the travel resistance caused by the resistance with a shoe face by forming slide sections near both ends in the longitudinal direction of a side edge section, and forming a gap capable of storing and holding lubricating oil between the center portion of the side edge section and the shoe face. SOLUTION: A plate 1 is kept in slide contact with a linear shoe face G at two slide sections 4 near both ends of a side edge 3. When lubricating L is supplied to the plate 1 and the shoes face G from the outside during the travel of a transmission chain, the lubricating oil L enters a slight gap S formed between the shoe face G and the center portion 3A of the side edge section 3 of the plate 1 facing the shoes face G, and it is stored and held here. When the plate 1 is moved along the shoes face G, the lubricating oil L located in the gap S gradually enters between the slide section 4 and the shoe face G to form an oil film between them, and the friction between the plate 1 and the shoe face G is reduced. When the lubricating oil L in the gap S becomes lacking, the lubricating oil L is taken in from the surrounding, thus the stable oil film can be maintained.

Title: Positioning method for conveyance means
Inventor: YAMADA KAZUO
IPC: B65G1/04
Filed: 1984-03-02
Abstract: PURPOSE:To improve the positioning precision of a conveyance means traveling between multi-layered compartment stockers by preparing a deviation-from-the- shelf memory and a current stocker location memory in order to obtain the actual positioning of the stocker from the current location and the deviation from the shelf. CONSTITUTION:Upon receiving a lift delocalization command (LDC), a lift operation controller 21 inputs a pulse S2 representing the turning angle value of a motor 27 through a transducer 29 into a current location counter 30 which identifies the current position of a conveyor lift and outputs the integrated value T2. Then the controller 21 instructs through a computation circuit 25 the motor 27 to drive the unillustrated conveyor lift toward the designated direction in such a way that T2 falls on in between another integrated values T2p and T2p' stored in the stocker location memory 22. Upon reaching the target stocker, the controller 21 reads the deviation-from-the-shelf value deltaK, and instructs the lift through the computation circuit 25 to make a movement for positioning. Thus the location precision is improved.
